Had the choice of either , my mates Gen 2 was running the CT long ti pipe , I prefered and chose the CT Meg , the Meg is straight up louder tho , so living with the CT is probably going to suit most better . I think the CT is great looking , and in 4-2-1-2 version is very nice , but for Gen 2 .The short may look tidy, but the long sounds better IMHO. I put the long on my gen2 and it sounds like an F1 car when revved up high. Listen to sound clips on youtube and you'll see or hear. My riding buddy said the meg long was the best sounding exhaust he ever heard over here in SOCAL where there are thousands of bikes with hyper exhaust!
